[PATCH v11 0/4] Add Intel LJCA device driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add driver for Intel La Jolla Cove Adapter (LJCA) device. This
is a USB-GPIO, USB-I2C and USB-SPI device. We add 4 drivers to
support this device: a USB driver, a GPIO chip driver, a I2C
controller driver and a SPI controller driver.

---
v11:
 - switch dev_err to dev_dbg for i2c-ljca driver
 - remove message length check because of defined quirk structure
 - remove I2C_FUNC_SMBUS_EMUL support

v10:
 - remove ljca_i2c_format_slave_addr
 - remove memset before write write w_packet
 - make ljca_i2c_stop void and print err message in case failure
 - use dev_err_probe in ljca_i2c_probe function

v9:
 - overhaul usb-ljca driver to make it more structured and easy understand
 - fix memory leak issue for usb-ljca driver
 - add spinlock to protect tx_buf and ex_buf
 - change exported APIs for usb-ljca driver
 - unify prefix for structures and functions for i2c-ljca driver
 - unify prefix for structures and functions for spi-ljca driver
 - unify prefix for structures and functions for gpio-ljca driver
 - update gpio-ljca, i2c-ljca and spi-ljca drivers according to usb-ljca's changes

Wentong Wu (4):
  usb: Add support for Intel LJCA device
  i2c: Add support for Intel LJCA USB I2C driver
  spi: Add support for Intel LJCA USB SPI driver
  gpio: update Intel LJCA USB GPIO driver
